This book was released on 2009 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le vignoble champenois, afin de contenir et de réduire la pollution des eaux de ruissellement chargées en polluants, celles-ci sont souvent collectées dans des bassins. L’utilisation de plantes aquatiques dans ces bassins pourrait être une technique efficace pour éliminer les nombreux pesticides contenus dans ces eaux. L’étude a porté sur la sensibilité et l’efficacité de macrophytes (Cabomba aquatica, Callitriche palustris, Elodea canadensis, Lemna minor et Spirodela polyrhiza) et d’algues unicellulaires (Scenedesmus obliquus et Scenedesmus quadricauda) dans la remédiation de pesticides. Les macrophytes aquatiques placées dans les milieux contaminés ont permis la disparition maximum de 48 μg.g-1 de MF de diméthomorphe, 33 μg.g-1 de MF de pyriméthanil, 53 μg.g-1 de MF de glyphosate et 7 μg.g-1 de MF d’isoproturon, après 4 jours d’exposition. L. minor s’est avérée être la plante la plus performante dans le prélèvement des fongicides. L’influence de différents paramètres sur les capacités d’épuration de L. minor et/ou S. polyrhiza vis-à-vis du diméthomorphe a été étudiée (concentration initiale en fongicide, densité des plantes, température, intensité lumineuse). L’augmentation de la température et de l'intensité lumineuse favorise le prélèvement du fongicide par L. minor, indiquant que celui-ci pourrait être lié à un métabolisme actif dans la plante. Les mécanismes mis en jeu par le végétal pour détoxiquer le diméthomorphe (Cytochrome P450 et les Glucosyltransférases) semblent confirmer cette hypothèse

Download or read book Pesticides in Aquatic Environments written by Mohammad Khan and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water covers about two-thirds of the surface of earth, but only 0.627 percent of this water is the sweet surface and subsurface water available for the survival of freshwater organisms including man (1,2). Some of this fresh or sweet water lies in practically uninhabitable regions (rivers: }1ackenzie in Canada; Amazon in Central America; Ob, Yenesey, and Lenta in Siberia, etc.). Also, most of the major rivers (the Mississippi in U.S.A., the Rhine in Europe, the Volga in U.S.S.R., the Ganges in India, etc.), because they flow through agricultural land or urban and industrial areas, have become highly contaminated with chemicals (3). This leaves us with shrinking resources of sweet surface water. In the United States, the dependable supplies of this water are already dwindling in cities like New York and Los Angeles and states like New Mexico and Texas (3).

Download or read book Pesticides Remediation Technologies from Water and Wastewater written by Mohammad Hadi Dehghani and published by Elsevier. This book was released on 2022-04-26 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides Remediation Technologies from Water and Wastewater focuses on environmental aspects and health effects of pesticides, the use of conventional and AOPs technologies, and adsorption processes and nanomaterials for the removal of pesticides from water and wastewater. The deterioration of water quality is of great concern due to its effects on aquatic organisms, humans and the ecosystem. Among the pollutants, pesticides are a major concern in villages and farm land. This edited book bridges the gap between old and new knowledge about the categorization of pesticides, the presence of them in water, wastewater, soil and foods, and new methods to detect them from water matrices. This edited book provides the necessary basic knowledge to new researchers who want to learn about pesticides and the ways to eliminate them in aqueous matrices. Moreover, it is also a helpful resource for mature researchers in this field, providing them with new trends in water and wastewater treatment processes, preparation and application of novel adsorbent materials. Includes methods for effectively removing pesticides from potable water and water bodies Provides techniques that are eco-friendly and that do not use toxic chemicals and are lower in cost Presents information needed to identify severe health effects on human beings and aquatic animals

Download or read book Handbook of Research on the Adverse Effects of Pesticide Pollution in Aquatic Ecosystems written by Wani, Khursheed Ahmad and published by IGI Global. This book was released on 2018-10-05 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain types of pesticides are widely used in agriculture in all parts of the world due to their relatively low cost, broad spectrum of activity, and high efficiency. These pollutants contaminate not only the surrounding soils and water but, in many cases, also enter into the drinking water. The Handbook of Research on the Adverse Effects of Pesticide Pollution in Aquatic Ecosystems provides emerging research exploring the theoretical and practical aspects of the prevention of accumulation of toxic pollutants such as agrochemicals and organochlorine pesticides in aquatic ecosystems and applications within ecology and agriculture. Featuring coverage on a broad range of topics such as pesticide monitoring, metabolites, and risk assessment, this book is ideally designed for scientists, researchers, engineers, policymakers, agricultural specialists, industrialists, academicians, and students seeking current research on the risks of water contaminants in small ecosystems.

Download or read book Phytoremediation Role of Aquatic Plants in Environmental Clean Up written by Bhupinder Dhir and published by Springer. This book was released on 2013-07-24 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contamination of the different components of environment through industrial and anthropogenic activities have guided new eras of research. This has lead to development of strategies/methodologies to curtail/minimize environmental contamination. Research studies conducted all over the globe established that bioremediation play a promising role in minimizing environmental contamination. In the last decade, phytoremediation studies have been conducted on a vast scale. Initial research in this scenario focused on screening terrestrial plant species that remove contaminants from soil and air. Later, scientific community realized that water is a basic necessity for sustaining life on earth and quality of which is getting deteriorated day by day. This initiated studies on phytoremediation using aquatic plants. Role of aquatic plant species in cleaning water bodies was also explored. Many of the aquatic plant species showed potential to treat domestic, municipal and industrial wastewaters and hence their use in constructed wetlands for treating wastewaters was emphasized. The present book contains five chapters. First two chapters provide information about types of contaminants commonly reported in wastewaters and enlists some important and well studied aquatic plant species known for their potential to remove various contaminants from wastewater. Subsequent chapters deal with mechanisms involved in contaminant removal by aquatic plant species, and also provide detailed information about role of aquatic plant species in wetlands. Potential of constructed wetlands in cleaning domestic and industrial wastewaters has also been discussed in detail. The strategy for enhancing phytoremediation capacity of plants by different means and effectiveness of phytoremediation technology in terms of monitory benefits has been discussed in last chapter. Last chapter also emphasizes the future aspects of this technology.
